02Description

Species Profile

The crevalle jack, also known as the common jack, black-tailed trevally, couvalli jack, black cavalli, jack crevale, or yellow cavalli is a common species of large marine fish classified within the jack family, Carangidae. The crevalle jack is distributed across the tropical and temperate waters of the Atlantic Ocean, ranging from Nova Scotia, Canada to Uruguay in the western Atlantic and Portugal to Angola in the eastern Atlantic, including the Mediterranean Sea. It is distinguishable from similar species by its deep body, fin colouration and a host of more detailed anatomical features, including fin ray and lateral line scale counts. It is one of the largest fish in the genus Caranx, growing to a maximum known length of 124 cm and a weight of 32 kg, although is rare at lengths greater...

Crevalle jack populations face significant pressure from intensive commercial and recreational fishing throughout their range, with juveniles particularly vulnerable in coastal nursery habitats. Coastal development and pollution degrade critical spawning and nursery areas, while climate change affects prey availability and ocean conditions that these highly migratory fish depend upon.
